Summary
Pillow: Heap out-of-bounds write `Image.paste()` / `Image.crop()` via signed coordinate overflow
Details

Pillow is a Python imaging library. Prior to 12.3.0, Pillow public image coordinate APIs can trigger a native heap out-of-bounds write when given coordinates near the signed 32-bit integer limits in Image.paste(), Image.crop(), or Image.alpha_composite(). This issue is fixed in version 12.3.0.
